7 Application filed August 8, 1913. Serial No. 783,684.

Tb (ZZZ whom it may concern Be it known that l, FREDRIOK H. KAN- ivixc, a citizen of the United States, residing at Hopewell, Washington county, lll issouri, have invented a certain new and useful Impi venient in Wrenches, of which the folloving is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to wrenches, and has for its main object to provide a wrench that comprises a stationary jaw and an adjustable jaw that are held in operative relationship by means of a pressed metal body portion.

Another object is to provide a wrench in which the adjustablefjaw is reinforced on three sides against excessive strains.

Still another object is to provide a wrench that is light and strong and which may be produced at a low cost of manufacture.

Other objects and desirable features of my invention will be hereinafter pointed out.

Figure 1 ofthe drawings is a side elevational view of'a. wrench constructed in accordance with my invention; Fig. 2 is a front elevational view thereof; Fig. 3 is a top plan view; Fig. 4 is a horizontal iional view taken on the line -l.---i of Fig. 1; and Fig. 5 is a plan view of the blank that used to form the body portion of thc wrei'ich.

Referring to the drawings which illus irate the preferred form of my invention, A (h signatcs the body portion of the wrench, and B and I designate, respectively, the stationary and adjustable jaws that are mounted in said body portion A. The body portion A is formed from a blank or flat piece of sheet metal that is cut into the shape shown in Fig. 5, the edges thereof being turned up as at a except for a short space at the upper end thereof, said blank being adapted to be bent or pressed around the aws l5 and C so as to hold them in operative relationship. Rivets or other suitabhfastening devices 1 are passed through the shank 2 of the jaw B and the pressed meta l. body portion so as to rigidly connect said parts.

The adjustable jaw C is provided with a shank 3 that of less width than the 'WOIkengaging portion thereof, and said shank is adapted to be adjusted vertically in the space 4 formed between the rear face of the shank 2 and the rear wall of the body portion A, said shank beingvprovided with a threaded extension 5 that cooperates with an adjusting nut 6 that is mountedin a slot 7 formedin the body portion A.

The lower part of the body portion A is reduced in size so as to form a convenient handle a said handle being hollow. An offset extension 8 of the shank 2 extends partially into the handle a so as to strengthen and reinforce the handle at the point of connection with the body portion A. An extension a at the upper end of said body portion A partially surrounds the shank 3 of the jaw C and the forward edges.

thereof bear against the shoulders formed at; the junction of the work-engaging por tion and said shank and thus reinforce said jaw and protect it against excessive strains in the three directions indicated by the arrows :0 in Fig. 3. i

From the foregoing it will be seen that I have produced a wrench that is light exceptionally strong because of the reinforcements at the points of greatest strain, and that comniises few parts which may be manufactured cheaply and assembled easily.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a wrench, a stationary jaw that is proided with a reduced shank having an offsct portion at its lower end, a movable jaw that is provided with a reduced shank, a pressed metal body portion that surrounds said shanks and extends some distance below the offset portion of the shank on the stationary jaw so as to form a handle, an extension on said body portion that entirely covers three sides of the reduced shank on the movable jaw, vertically-disposed faces on said extension that bear against the rear shoulder of the movable jaw face when said jaw is moved away from the stationary jaw, and means for moving said movable jaw.

In testimony whereof I hereunto affix my signature in the presence of two witnesses, this twenty ninth day of J ulf' 1913.

FREDRICK H. KANNING.
